Anderson localization: hierarchy of statistical anomalies E l a Effect of commensurability of the lattice constant a and the Fermi-wavelength  This effect is not present in the continuous model. Localization length sharply increases in the vicinity of E=0 and sharply decreases in the vicinity of E=1 F.Wegner, 1980; Derrida & Gardner, 1986 Titov, 2002 Deytch et al 2003 At E=0 (f=1/2): At E=1 (f=1/3 or 2/3): The width of anomalous region

Generalized Fokker-Planck equation The function  is found from the generalized Fokker-Planck equation: where Is the localization length without anomalous contributions Result of the super-symmetric quasi- sigma model (Ossipov, Kravtsov 2006)

Where are the anomalous terms? The term has a part that emerges only at f=m/(p+2)

Problem of continuous degeneracy W is the Whittaker function How to fix the function C  Q: A: Smoothness of  (u  with all the derivatives + some miraculous properties of the Whittaker function

Final result for the generating function WHY SO MUCH OF A MIRACLE? WHAT IS THE HIDDEN SYMMETRY? What is the new properties of the anomalous statistics?

Conclusion  Statistical anomalies in 1d Anderson model at any rational filling factor f.  Integrability of the TM equation for GF determining all local statistics at a principal anomaly at f=1/2.  Unique solution for the GF in the infinite 1d Anderson model.  Hidden symmetry that makes TM equation integrable?
